Vcf - Roland JX-08 Owner's Manual

VCF SECTION
This section controls the filter to adjust the sound of the
tone. VCF stands for "voltage conttrolled filter" and here
there are two filters (hi pass and low pass) plus
modulation and control options ro create with.
HPF
0–3
Specifies the cutoff frequency of the high-pass filter.
CUTOFF FREQ
0–10
Sets the cutoff frequency of the low-pass filter. This
gives the sound a more mellow feel, by removing
frequency components that are higher than the cutoff
frequency.
RES
0–10
Increasing the value emphasizes the frequencies
around the cutoff frequency for a more unusual sound.
Excessively high settings can produce oscillation,
causing the sound to distort.
LFO
0–10
Sets how much LFO modulation is applied to the cutoff
frequency.
KEY FOLLOW
0–10
Changes the cutoff frequency according to the keys you
play.
With a larger value, playing notes above C4 (middle C)
on the keyboard increases the cutoff frequency the
higher you go.
ENV
0–10
Sets how much effect that the envelope you selected
using the MODE switch has on the cutoff frequency.
MODE
1 (NORMAL)
1 (INVERSE)
2 (NORMAL)
2 (INVERSE)
Selects the envelope and polarity that controls the VCF.
